ALVIN J. KERSH, OF OAKLAND, TEXAS.

PLOW-COLTER.

SFECIFICATION forming part of Letters Patent No. 251,602, dated December27, 1881.

Application tiled September 29, 1881.

To all whom it may concern Be it known that I, ALVIN J. KERsH, a citizenof the United States, of Oakland, in the county of Lavaca and State ofTeX-as, have invented a new and valuable Improvement in Colters forFlows; and I do hereby declare that the following is afull, clear, andexact description ot' the construction and operation ot' the same,reference being had to the annexed v drawings, making a part ot' thisspecification, and to the letters and gures ot' reference markedthereon.

Figure l of the drawings is a representation of a perspective view ofaplow with my improved colter attached, and Fig. 2 is a side view ot'the colter.

This invention has relation to colters for plows; and it consists in thenovel construc- .tion and arrangement of the plow-standard, theplow-point, and a removable colter adapted to be secured to either sideofthe standard in front ofthe plow-point, to form a cutter or share, aswill be hereinafter fully described, and pointed out in the claim.

Referring by letter to the accompanying drawings, Adesignates theplow-standard; B, the shovel or plow-point, and O the removable colter.The colter O has an upper rear arm, perforated at a a, by which it maybe bolted to either side of the plow-standard in front of the shovel orpoint. The rear outline, b, ofthe colter conforms to the front curvatureofthe (Model.)

shovel or point. The cuttingedge ot' the colter is convex, as shown,running toa point below, and notched above at c. to form a point, d. Thecolter forms a landside for the plow, and, as before stated, isremovable, and may be applied to either side of the standard.

A one-piece standard and landside having a recess to receive the shankot the colter, the latter having a forward projection that rests uponthe share, is not new, and is not broadly claimed herein. Protection isasked only for the limited construction hereinafter specicall y claimed.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent', is- In aplow, the combination, with the standard A and shovel B, of the colterattachment consisting` ofa pointed colter or cutter forming a landsidef'or the shovel, having its rear outline curved to conform to theface-curve ot' the shovel, the upper rear perforated arm notched ate toform the point d, and adapted to be secured to either side ot' thestandard, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence ot' two witnesses. Y

ALVIN JACOB KERSH.
